17.

 

Before lowering the vehicle, measure from the top of the wheel well directly above the center line of the wheel 
to the top of the tire, (Figure 7). Record this measurement as (A) in Table 1. Subtract 3 inches from A and record 
this number. 

 

NOTE:

 

It can be helpful to place a piece of painter’s tape at the top of the wheel well directly above the 

centerline of the wheel and measure from there. 

 

18.

 

Set the truck on the ground and drive forward and backward a few times to settle the suspension. Measure 
again from the top of the tire to the top of the wheel well as in the step above and record this measurement as 
(C) in Table 1. 

 

NOTE:

 

If (C) is larger than (B), the ride height is too tall. This can be caused by shocks or shock spacers that are 
too long, stacked shock spacers, spring preload devices, or any combination of the above. 

Failure to use compatible shocks to limit the vehicles front suspension may cause over-extension, which 
as a result can cause damage to ball joints, uni-balls, tie rods, and/or CV axles, along with other related 
safety issues. 

Warranty on Cognito products will be void if the vehicles front suspension is not properly limited to the 
above max ride height calculation.
